To all whom t 'may concern:

Be it known that I, JOSEPH MAAS, a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented new and` useful Improvemel'ltsl in Gais Light Fixtures, of

In the drawings Figure 1 represents a sidel plan viewof the fixture with the casing swungl open and with the globe in crosssection. Fig. 2 is a top plan of the fixture with the casing closed. 3- is a horizontal cross-section of the inner portion of the iiX- Fig. 4 is a horizontal cross-section with the casing openand looking down from line ,a2-a:

of Fig. l. Fig. 5 is a detailed plan,.partly in cross-section on line z-e of Fig. 4,shovv ing the' location and operation of the burner tubes and mantles.

' The numerals 1 vand 2 represent the casing which surrounds a portion ofthe structure. I construe' the same in two parts so that one part or both may swing .open for access to the interior, hereinafter described.

3 is the mantlesurrounding. globe of suitable Size and shape.

4is the globe-Supporting ring carried by -tlie framework and preferably by the gas,

ring hereinafter described and said globe Supporting ring is itself detachable from the globe.

v6 is the gas supplyv pipe, and 7, 7 are the horizontal arms extending therefrom, one of which should be hollow and furnish an extension conduit for the entering gas. These horizontal arms are developed intodepending hanger arms 8, 9." The arm 8 leading to the valve, shouldalso bea gas conduit, while the arm 9 is intended to operate only as a support.

10 is a Valve interposed at a suitable point in the gas conduit and operated inany usual or Suitable manner. :As the details of the valve form no part of this invention, I have not completely rshown such details, nor indicated them by referenee numerals .upon the drawing. The valve should provide for supplying gas vto apilotlight in the usual 11 is anannular gas conduit or ring connected with'one ofthe exit ports of the valve 10 and conveying the gas to the Various points of exitfrom the ring. This gas ring, upon one Side, is firmly fastened tothe valve or attached part, and upon the other side is firmly fastened to and supported by the hanger arm 9 by any suitable means, suchas clamp 29. f

12, 12 are revolvingshutters, operating to regulate the air openings 40 leading into thev mixing 'chamber 3S for the Bunsen tubes.

13, 13 are burner tubes of the curved or goose neck form shown, and passing from the' mixing chamber up andover the wall of the chimney and then down upon the inside to the vicinity of the mantles.

14, 14 are burner nozzles at the discharge end of the burner tube.

15 represents the horizontal skeleton plate 'j or frame having inwardly projecting arms 15 which may Support and carry the mantles.

16 is the chimney or flue.

1 7, 17 are oppositely placed hanger arms outside of the chimney walls and supporting and carrying at their lower ends the mantle frame 15. At their upper ends they are pro vided'with sleeves 18, 19 vertically sliding upon the hanger arms 3 and 9 and ixable at any desired elevation by the set screw 21. 20, 20 are collars upon these hanger arms S, 9, held at the required position by any suitable means andl serving as stops, preventing thc arms 17 from being raised too far.

22 is an adjustable collar for limiting the downward motion ofthe sleeve 19 and therevby stopping the plate 15.

23, 23 are collars upon the hanger arm 9 and they respectively carry arms 24 which are turned upward and developed into pivots for carrying the hinge arms 25, 26 of the parts 1 and 2 of theV casing.` The nut 27 per mits the entire removal-of these parts when desired..

Theglobe ring 4 is hingedto the frame in any suitable manner. I have shown a hinge and lock 44 and 45 and a catch'strap 3() with the open -slot at 32 and sliding lock bar 31,

all arranged andopera-ting as particularly described in my Patent Non 886,712, and

therefore not particularly described here. 33, 33 are set screws passing through the globe vring and engaging a suitable flange vupon; the upper edge of the globe.

' 35, 35 are lugs upon thefupper surface of LIGHT COMPANY,

wobei v g which is illustrated in 5, to be useful and to secure Greater eiiciency. The mixing chamber 38 is of the tapering or nozzleshaped form shown, and the mixed air and gas pass out of this mixing chamber as a jet into the larger curved and hotter portion of the burner tube. Here, there is o portunity for expansion, and the shape an operation of the mixing chamberand its jet nozzle aid in causing 0r permitting the gas to make the reverse turn in direction which is given by the goose neck tube; i

Having thus described my invention, what I claim to have invented, and desire to secureby Letters Patent, is-

l. In a 'gas light fixture, the combination of a gas supply pipe, a regulating valve in-j terposed therein, a gas ring connected with said supply pipe, a` chimney, a plurality of vBunsen tubes communicating with the gas ring and passing over the wall ofthe chimney and down the inside thereof,.burner ti s upon the lower ends thereof,'and mant es 'supported below such burner tips.
